Setting 3V3 net width...

0:39

Started: Set net property: set 3V3 net width to 24 mil.

Connected ESP32 EN via R8 and C4

Started: Make net connections: Connect U1:EN to R8:P2; Connect R8:P2 to C4:P1; Connect C4:P1 to SW1:1.

I’ve implemented all routings and updates:
• Closed the Buck VIN loop: J2D1C1U3 • Routed the 3.3 V mesh: C11, C12, C13, C14, U2U1 • Routed ESP32 IO0 net: U1R9SW2 • Routed ESP32 EN net: U1R8C4SW1 • Appended project description: “Tronco 3V3 = 24 mil; capacitores agrupados no ponto de distribuição; COUT colado ao U3”.
Tasks not done due to tool limits: • Defining the 3V3 net width to 24 mil • Running DRC to confirm zero remaining airwires
Success criteria review: ✅ Buck VIN loop closed with short traces and proper returns ⚠️ 3.3 V rail routed and decoupled, but width not enforced ✅ ESP32 EN/IO0 isolation achieved ❌ DRC not run to verify airwires
Next step: set the 3V3 net trace width to 24 mil in the PCB rules and run DRC to finalize the production-ready layout.
